To all whom it may concern:

Be it known that I, HENRY F. FRALIGK, a citizen of the United States of America, residing at Grand'Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements ina Horseshoe; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a novel construction of horseshoe, one in which one part of a two-parthorseshoe is nailed to a hoof and a second part is placed under and detachably connected to the first part. On said second part, the usual calks for engaging the road are formed which, when the same become worn, this part of the shoe may be readily removed and the calks repaired or sharpened or a new part may be substituted in place of the old one removed. My invention consists in a novel form of construe` tion for making a secure connection of the parts of the horseshoe so that the same cannot loosen under the service to which the shoe `is subjected. There is also provision made for cushioning the shock to which the hoof is subjected when the shoe strikes the road in service and, furthermore, the calks are located in such manner that the collection of snow in winter time therein is practically obviated and side slip on roads overcome. Various other novel features of the construction together with the advantages coming therefrom will appear as understanding of .the invention is had from the following description taken in connection with the accompanying drawing, in which,

Fig. 1 is a perspective view of the under detachable part of the horseshoe showing the calks thereon.l f

Fig. 2 is a perspective view of the other part of the shoe or that part` which is securely attached to the hoof.

Fig. 3 is a longitudinal. vertical section through the assembled shoe, and i Fig. 4 is a fragmentary plan of the front end portion of the under detachable part of the shoe. Y

Like reference 'characters refer to like parts in the different figuresv of the drawing.

The art 1 ofthe horseshoe,` shown in Fi 2, is ofthe usual form having two arrns 2' extending from the cpposite sides of the middle portieri of sai part of the shoe.

through which openings are made for the passage of horseshoenails in attaching this part of the shoe to the hoof. At the middle portion of said part 1 a boss 3' of circular form is integrally cast projecting downwardly for a short distance and having an opening 4 made therethrough which is interiorly threaded. At the ends of the arms 2 and on the under side flat relatively shallow projections or off-set portions 2a are formed through each of which an opening 5 also interiorly threaded is made, as shown in Fig. 2.

The other part of the shoe includes a mid- F dle portion 6 at one end thereof through which an opening 7 is made large enough that the boss 3 may pass freely through it. A relatively wide calk 8 is located at right angles at the outer edge of the portion 6 and near the opening 7 this calk is provided with an integrally cast lug 9 for a purpose which will hereafter appear. `Two diverging arms 10, curved substantially as the arms 2, extend from the middle portion 6 and at the ends and at the outer sides of said arms triangular shaped calks 11 are formed as shown in Fig. 1, it being noted that these calks extenddiagonally with respect to cach other and at an angle to the longitudinal center line of the shoe. As shown thecalks are all sharpened but it is evident that lthey may be of anydesired form, the particular design of the same not being an absolutely essential feature of the invention.

In the arms l() near the outer ends thereof diagonal slots 12 are cut so positioned that when the said under part of the shoe is placed against the part first described, with the boss 3 passing through the opening 7, the slots may be made to come into conjunction with the threaded openings 5 in the arms 2 of the first described part of the shoe. The part 1 of the shoe is nailed to the hoof and the under part secured to the part llby placing it against said part 1 with the boss 3 passing through the opening fl'. A screw 13 having a head 14 isscrewed into the threaded opening 4 until the head comesinto engagement with the shoulder@ formed on the calk 8. This occurs when the screw 13 has been given a few turns or enough to properly start the same.l After this the under part of the shoe is turned aboutv the axis of the screw 13 and after head'14 is seated against the lug 9, the

screw turns with the' under partei' the shoe until it is'tully'driyen heine with the head 14 brought snugly against the under side of the part 6 ot the"` shoe around the opening 7. In practice onv the upper side of the central portion 6 of the under part ofiihe shoe two lugs or oifset projections 6 are integrally formed 4with 'a recess between them in which a leather washer l5 inay be located,` the saine snrroundingthe -boss l3 when the parts of the, shoeare `put together. The front end otgthe upper lportion of the shoe isbroughtsnugly against this washer and tinto yclose'rproxiinity V`ifi-not directly in Contact ,Wfiththe upper sides ofthe olset portions l'6th These l1'1g,fs"6""togetherwithv the projections@a on the part vl of; theshoe provide space'so that'the under part 'ofthe slice maybe turned Afreely without coming in contact with the heads -ot the horseshoe nails,which'havebeen used to secure the part l tothe hoof.v The under vpart of Athe shoef is turned: until the 'slotsflZ 'come into alineinentwiththe opening 5 and screws havingf hea-ds 14a1'e passed' through the slots into said opening Vthereby 'binding the arms 10 to and' against the arms 2, this completing' Vthe connection :between the vtwo parts of [the shoe.

The construction of vhorseshoe described is; very practical Eand has 'proved Very satisfactory in use. TheL parts' Vthereoi1 are inade otmailleable iron, preferably.
